什么是混帐“快照”？ [英] What is a git "Snapshot"?

问题描述

官方的Git文档说：

$ git diff test

这会告诉你什么是不同的当前工作目录和'test'分支上的快照

This will show you what is different between your current working directory and the snapshot on the 'test' branch

作为一个新手，这是非常令人困惑的。我从来没有听说过快照这个词。它们是指测试分支的HEAD吗？

As a newbie this is very confusing. I've never heard of the term snapshot. Do they mean the "HEAD" of the "test" branch?

推荐答案

快照是某事物的状态（例如文件夹）在特定的时间点。在这种情况下，快照意味着测试分支的当前内容，这不一定是头版本。

A snapshot is the state of something (e.g. a folder) at a specific point in time. In this case, snapshot means the current content of the test branch, this doesn't have to be the head revision.
